Abstract

Polyaniline(PANI)/pelyacrylronitrile(PAN) nanoweb was obtained by electrospinning and in situ polymerization. The electrospinning dope was prepared through dissolving purified PAN in dimethylsulfoxide. To obtain PAN nanoweb of the proper morphology for PANI in situ polymerization, the dopes were electrospun with varying voltage, tip-to-collector distance(TCD) and dope concentration. Then, PANI, one of the conductive polymers, was polymerized on the surface of PAN nanoweb by in situ polymerization. The relationship between the electrical conductivity of PANI/PAN nanoweb and several polymerization variables was investigated. Aniline concentration, diffusion time, polymerization time, and molar ratio of aniline to oxidant (ammonium persulfate) were handled. The electrical conductivity was measured by 4-point probe method.
